In the drawings I have shown at'll a base frame which is hollow and oblong in form, the end portion 12 of which is of approxlmately cylindrical form and a shaft 13 is mounted longitudinally of the base frame 11 inbearings 14. A beveled gear 15 is secured to said shaft within the cylindrical portion 12 of the frame as shown in Fig. 1, and adapted to operate in connection with another beveled gear 16 secured to the lower end of a vertical shaft 17.

Mounted on the shaft 17 is a vertical sleeve 18 which is permanently mounted in the top central portion of the cylindrical portion 12 of the frame as shown at 19, and the upper end portion of the sleeve is provided with elongated gear or sprocket teeth on its outer face as shown at 20 in Fig. 7 of the drawing. Rotatably mounted on thecentral portion of the sleeve 18 is a conical workpiece supporting member or table 21., comprising a central sleeve portion 22, a top portion 23, a downwardly and flaring rim portion 24 and adjacent to the bottom of the sleeve portion 22 is an annular flange 25.

A supplemental or disk-shaped frame 26 is mounted on the upper end portion of the sleeve 18 and provided with a raised keeper 27 and with a raised block 28, as shown in Fig. 9 of the drawing, said .block being provided with an elongated rectangular aper'' ture 29 and at the top of which is a beveled track or slide-way 30.

A slide or jaw member 31 is movably mounted in the aperture 29 and a carriage 32 is slidably mounted in the beveled track or slide-Way 80 as clearly shown in Figs.

till

5, 6 and 9 of the drawing. The carriage 32 is provided with two upstanding cars 83 in which is movably mounted a longitudinal rod 34, one end of which is secured to the keeper 27 as shown at 35., and a spial spring 36 is mounted between the keeper 27 and one of the ears 33 and two adjusting and lock nuts 37 are mounted on the rod 3e outwardly of the other of'said cars 33, the end of said rod being forked to receive a link 38, one end of which is pivoted within said forked portion of rod shown. at 39 and the other end of said link is pivoted to an upwardly directed fork 4 on a lever 41 pivotally mounted in the forked end 4&2 of the carria cler '"ly shown in Figs. 3.. o", 6 and 8 of "he drawing. The free end of the lever 3:1 is larged to form a hammer face 428 the function of which is hereinafter set on.

The inner end portion of is provided in the bottom face an antiction roller 4+1. and a s1 friction roller 4:5 is mounted in a aperture 46 in the inner face 0 or member 31, and can member 4:?

illlSViEi be i I F the carriage o2 revenue ble tubes 64, one of which is indicated in dotted lines in Fig. 3, and the upper end portion of another of which is shown in full lines in Figs. 5 and 6 The screw cap ends 65 of the tubes 6 1 are adapted to enter the apertures 63 in the plates 61, and the larger or flattened ends of said tubes are adapted to be held between the separate pairs of pins 60 with the folded ends 66 of said tubes resting upon the periphery of the supplemental or disk-shaped frame 26. a

The member 21 is given an intermittent rotary movement on the sleeve 18 and controlled by the pawls 58, and an intermittent vertical movement by a plurality of downwardly directed pins 67 secured to the annular flange 25, four of which are preferably employed. A cam member 68 is proi a plurality of raised portions .orresponding number of recessed it) in connection with which the 67 operate. The member 21 is held in its raised position by the pins 67 resting up-n the flat faces 1 on the top of the ed portions 69, and when said pins are the last named position the member 21 provided with independentncsm faceswehiuwiii assume a position similar to that indiand is secured to upper end 3 rtion of the shaft 17 in such position th. the cam face e8 will operate in connection with the roller 4 1, and the cam face 39 in connection with the roller A supplemental jaw member 50 is mount ed in the slide or member-31 and provided with inwarr y which are mounted springs 52 which operate in apertures 58 in the jaw member 31, and the jaw member 50 cooperates with the slide or jaw member 31 hereinafter described. A vertical pin 54" is secured centrally of the member 31 and passes downwardly through an aperture 55 in the supplemental or diskshaped frame 26, and one end of a spiral spring 56 is secured to said pin and to a screw 57 secured to the frame 26 as clearly shown in Fig. 6 of the drawing, and this spring serves to move the slide or aw member 31 in one direction.

The workpiece supporting member 21 is provided on its top face with two pawls 58 which operate in connection with the ratchet teeth 20 on the sleeve 18 as clearly shown in Fig. 7, and these pawls are normally held in engagement with said teeth by springs 59. Mounted on the face of the conical or flaring portion 24 of the member 21 adjacent to the top face thereof are a plurality of pairs of outwardly directed pins 60 below each pair of which an ill-shaped plate 61 is adjustably secured as shown at 62. to the face of the conical or flaring portion 2%, the protruding portion of said l.-shaped plate being provided with an aperture 63. and these plates and the separate pairs oi pins 60 form supports and guides for flexicated in Fig. 6 of. the drawing. The workpiece supporting member 21 is given its intermittent rotary movement by the raised portions 69 of the cam member 68 striking or hearing on the pins 67 in the oscillation of said cam member, as ,hereinafter set out.

The cam member 68 is'provided on one side thereof with an extension 72 in which is secured a downwardly directed pin 73 which passes through an elongated aperture 7% in the top of the base frame 11 and a crank arm 75 is pivoted to the frame 11, as shown at 76, and provided at its free end with an upwardlv directed arc-shaped portion 77 in connection with which the pin 3 operates. The crank 75 is given an oscillatory movement by a downwardly directed pin 78 operating in an aperture 79 in the crank arm 75, and this oscillatory movement of the arm 75 will correspondingly move the pin 73 to give the cam member 68 a rotary, oscillatory movement.

At one side of the base frame 11 is an upwardly directed clip feeding device 80 which is adapted to supply a plurality of elongated li -shaped clips 81 to the supplemental frame 26 of the machine.

The device 80 is composed of two approximately similar side parts 82 which are joined centrally, said parts being provided with a flanged base 83 through which screws or bolts 84 are passed forsecuring the device to the frame 11, and centrally of the flanged base 83 are upstanding box .members 85 which terminate at 86, and which are provided with web constructions 87 which join the box members 85 with a hopper-shaped top portion 88 also composed of separate similar side parts. The opposite sides of the hopper-shaped member 88 are closed by plates 89 set within the same and the sides of the device 80, as a whole are closed by vertical strips 90, these connections being made by welding, bracing, riveting or other- .wise. The front and back walls of the de-' vice 80 are provided with a plurality of vertical slots 91, 92 and 93 which extend through the separate parts of said device, as clearly shown in Figs. 1 and 3 Movably mounted between the separate parts 82 of the device 80 where they abut is a vertical blade 94, the top of which is beveled as shown at 95 and inclined downwardly and inwardly, and a plurality of transverse blades 96 are secured tothe blade 94 as shown in Fig. 3, and are adapted to operate in the slots 91, 92 and 93 in the vertical movement of the blade 94.

The blade 94 is provided at its lower end with a link lever 97 which is pivotally connected thereto as shown at 98, and the lower .ing and the following statement.

end of said lever is'provided'with an elongated aperture 99 through which is passed a pin 100 secured to the free end of a crank 101 mounted on the shaft 13. This construction serves to move the blade 94 vertically in the device 80 in such manner as to pick up a number of the clips 81 as shown in Fig. 3 of the drawing and to permit of their discharge through an aperture 102 in one of the side walls 80 onto an inclined runway 103 as shown in Figs. 1 and 3 of the drawing. The runway 103 is secured to the' device 80 and extends toward the frame 26 and provided with a rectangular head104' such position that the runway 103 and said device extends toward the frame 26 at a tangent thereto or at right angles to the movement of the carriage 32 and the slide or jaw member 31, as clearly illustrated in Fig. 4 of the drawing. It will be under stood that a number of clip devices are placed within the hopper 88 of the clip feeding device 80 and the vertical movement of the blades'94 and 96 therein will cause the blade 94 to pick up a number of said clips as illustrated in Fig. 3, the blades 96 serving to break up or scufiie the clips in the device 80 to facilitate this operation.

The operation of my improved machine will be readily understood on a consideration of the foregoing description when taken in connection with the accompanying draw- It will be understood that the supplemental or diskshaped frame 26 and the clip feeding device 80 are stationary while the workpiece supporting member 21 has an intermittent rotary movement in the direction of the arrow m Fig. 4, and an intermittent vertical movement and the carriage 32 and the tionary j aw member.

slide or jaw member 31 have intermittent forward and backward movements on the frame 26. As the workpiece supporting member 21 rotates the tubes 64 are laced in position as is illustrated in dotte lines in Fig. 3,'prior to their passage into alinement with the slide or jaw member 31, and in this operation a sealed tubemay be re moved from the holder and an unsealed tube replaced therein by one operator, the holder or holders consists of the pairs of pins 60 and the L-shaped plates 61..

When a tube 64 is in alinement with the jaw member 31 as is illustrated in Fig. 3 of the drawing, the rotary movement of the workpiece supportin member 21 stops and at. this time the cam ace 48 on the cam member 47 operates in connection with the roller 44 to move the carriage 32 inwardly, the completion of which operation is indicated in full lines in Fig. 5 of the drawing. It will be noted that the folded top portion 66 of the tube is struck by, or pressed by the hammer face 43 of the lever 41 to straighten said folded end, after which the carriage 32 again moves into the position shown in dotted lines in Fig. 5 and in full lines in Fig. 3, and the workpiece supporting member 21 is moved upwardly. Prior to, or. at

roller 45 to move the jaw member 31 of the supplemental spring actuated jaw 50 thereof outwardly a slight extent to grasp a cllp in the manner shown in Fig; 5 of the drawing and to extend one side of said cli outwardly. It will be understood that t e clip referred to is supported on the upwardly directed extension .104 on the top of the rectangular head 104 of the runway 103.

In the next operation of the machine, the workpiece supporting member 21 moves upwardly to bring the folded end 66 of the tube beneath the side extension of the clip 81, and

this upward movement continues until the tube 64 with the clip thereon is in the position shown in Fig. 6 at which time the cam face 49 operates in connection with the roller 45 to move the jaw member 31 outwardly to compress said clip onto the folded end 66 of the tube 64, this result being accomplished by the jaw member 31, or the outer face thereof, and a downwardly directed portion 106 on the-Carriage 32, which forms a sta- In this last operation it will also be noted that the supplemental j aw member 50 is held against outward movement by the raised portion 104*, as clearly shown in Fig. 6 of the drawing, and when the jaw member 31 again moves inwardly by the spring 56, the tube 64 will be released and at this time the workpiece supporting member 21 moves downwardly and is again rotated one step, or one-eighth of a revolution to bring another tube placedmpon said member 21 into alinement with the jaw member 31 and the various parts that operate in connection therewith.

At each revolution of the shaft 13, the blades 94: and 96 are moved upwardly and downwardly in the clip feeding device 80 and the blade 94 being held-stationary to a in the elongated slot 79 by the crank 75, and

the engagement of the pin 73 of said member with the upwardly directed arc-shaped portion 77 and in said oscillatory movement of the cam member 68, the pins 67 carried by the workpiece supporting member move upwardly and downwardlyover the raised portions 69 of said cam member.

It will be readily understood that machine effects a great saving of time and labor and produces a 'more perfectly sealedjube or other article of the class specified, and although I have shown certain details of'construction for carrying my invention into effect, it will be apparent that I am not necessarily limited to these details, and various changes therein and modifications thereof may be made, withinthe scope of the appended claims, without departing from the spirit'of my invention or sacrificing its advantages. It will be understood that the shaft 13 which extends through one side of the base as shown in Fig. 1 may be rotated or driven in any desired manner by a pulley and belt construction, or gear construction from a suitable motor, but as this'forms no part of my invention the same has not been shown or described.
